gmnntoz Patented Oct. 1934 GLASSWARE FORMING MACHINE Leonard D. Soubier,Woonsocket, R. L, assignor to Owens-Illinois Glass Company, Toledo,Ohio, a

corporation of Ohio Application January 3, 1928, Serial No. 244,147Renewed July 9, 1932 58 Claims.

The present invention relates to improvements in glasswareformingmachines in general, and more particularly to that type in whichcharges of glass are periodically gathered by suction into the blankmolds at a charge gathering station.

An object of the present invention is to provide a machine of compactand simple construction embodying exceptional flexibility through whichit may be utilized in the production of a wide range of glassware.

A further object is to provide a glassware forming machine of the abovecharacter including an annular series of mold groups each adjustableindependently of the other whereby a single machine may be readilyadjusted to simultaneously produce several different types and sizes ofware.

Another object is to provide a machine of the above character whichmovement of the blank mold of each group is directly controlled bymovement of the finishing mold of the same group and in which both moldsare subject to periodic alternate movement toward and from each other.Thus,- the period of time utilized in transferring a. parison to thefinishing mold is materially decreased with a resultant increase inoperating speed and production.

A further object is to provide a machine of the above character in whichthe blank mold of each mold group moves downwardly at a predeterminedpoint to a blank transfer station and while approaching this station,opens so that the blank may immediately be enclosed in the finishingmold at the transfer station. There is further provided means associatedwith the blank mold whereby the point at which said mold begins to openmay be varied to thereby predetermine the period of, time during whichthe blank is subjected to atmospheric exposure. This feature is ofconsiderable value in that the condition of the glass or size of theblank or both, often necessitates a'chan'ge in the point at which theblank mold opens so that the glass is subjected to long or short periodsof exposure, these exposures controlling to a considerable degree thefinal thickness of the walls in the ware as well as the distribution ofglass therein.

A still further object is to provide a novel form of plunger mechanismembodying means in part controlling the application of vacuum and airpressure to the blank and neck molds, said mechanism being adjustable todifferent elevations whereby parts thereof may be readily repaired orreplaced.

The present invention further embodies means by which the period ofapplication of vacuum 'the charge gathering station, the blank moldsopening and closing the blank 'mold.

to the individual gathering molds may be readily adjusted as required bythe type ,of ware being formed on each individual head.

It is likewise an object of the present invention to provide a machineof the above character with a novel form of ware take-out mechanismindividual to the finishing .mold of each group and operable to transferware directly to a suitable handling device.

Other objects will be apparent hereinafter.

In the preferred embodiment, the machine comprises a stationary verticalcentral pillar rising froma circular hollow base 51 formed with anannular series of upwardly opening conduits 52 through which cooling airpasses from the hollow base 51 to chambers 53 for cooling the molds aswill be apparent hereinafter. These'chamb'ers 53,

' which are arranged in an annular series about the base 51 and formportions of the series of mold units, are rotatably mounted on thecircular base member 51 and carry a ring gear 54 which is driven tocontinuously rotate the mold carriage. On the vertical pillar 50 (Figs.1 and 2) is mounted a stationary cam 55 at a point in proximity to thecooling air chamber 53 for the purpose of operating mechanism to openand close the finishing molds. -A stationary cam 56 is fixed to thepillar 50 at a point spaced above the finishing mold cam 55 and controlsmechanismv which opens and closes the neck molds. Just above the neckm0ld cam 56,- a cam table 57 is rigidly mountedon the pillar 50 (Figs. 1and 2) to support a series of plunger actuating cams 58 on its upperside, and, a series of blowing air control cams 59 on its lower side.These cams (Figs. 1 and 2) correspond in number to that of the moldunits mounted on the mold carriage. A cam 221 (Fig. 1) actuates a valveto control the cut-off knife as will be described later. At the upperend of the stationary central pillar 50, is rigidly mounted a circularplate 60 which supports means for supplying air pressure and controllingapplication of vacuum to the several mold units as will be apparenthereinafter. 1

Each mold unit is supported on a frame comprising a pair of verticaltransversely spaced columns 61 having their upper ends bolted or andvacuum chambers 126 and 149, respectively, (Fig; 1) and their lower endsresting on and secured to the upper side of the cooling air chamber 53.These columns 61 are hollow and formed with transverse partitions 62adjacent their lower otherwise secured to the outer walls of the airends (Figs. 2 and 3) thereby providing in each column a relatively smallchamber 63 communieating through ports 6; with the interior of thecorresponding cooling air chamber 53. This con- -'struction and theprovision of hollow mold arms,

65 (Figs. 2 and 6), provide opposed guideways 66 in which a verticalslide 67 is mounted. A bearing block 68v Fi s! 1' and 2)-"is secured tothe' mner face of the slide 67 and is formed with a vertical 1 openingin which is rotatably mounted a bearing sleeve 69 having a screw threadconnection with an adjusting screw 70. A worm gear '71 is fixed to thesleeve 69 and bears against the under side of the bearing block 68. Thisworm gear 71 (Figs. land 5) is rotatable by manual operation of a handwheel 72 which is operable to rotate a worm .73 running in mesh withsaid worm gear '11. Rotation of the hand wheel 72 raises or lowers theslide 67 and thereby regulates the elevation of g the neck moldapparent.

The screw 70 (Figs. 2 and 6) is suitably supand gathering head as willbe ported in a bracket 85 fixed to the upper ends ofrack bars 74hereinafter described, said bars and the lower end of the screwextending through radial slots 86 (Fig. 19) in a cam plate '75, the

latter carrying a cam roll 8'7 at its inner end running upon thestationary neck mold cam 56 (Fig. 2). A coil spring 88 under compressioninterconnects the lower extended end of the screw 70 and a dependingfinger v89 arranged below the cam roll 8'7, said spring normallyyieldingly holding the plate at its innermost limit. Theouter end of thecam plate 75 is formed with transversely spaced tapered cam faces 90'which at all times slidably engage rollers 91 carried by arms 92connected through bearing plates 93 with the neck mold carrying arms 94,the latter supporting a. partible neck mold 95. The neckmold (Fig. 1) ismounted on a hinge pin '78 depending from a head 77 carried by an arm 76extending forwardly from the slide 6'7. A coil spring 96 (Fig. 19)interconnects the arms 92 and yieldingly holds the neck mold in closedposition.

The gathering head (Figs. 2 and 11) which is supported on the hinge pin'78 may comprise a circular frame '79, in which a downwardly taperedsleeve 80 is removably arranged,the latter providing a seat on which theplunger rod 81 rests at intervals. The arm 82 supporting the gatheri'nghead, is connected to a collar 83 non-rotatably mounted on the hinge pin78 and is also connected to the head 77 (Figs. 2 and 11) to insure rigidsupport for the gathering head.

The blank mold sections 100 (Figs. 11 and 21) are connected through arms101 to bearing disks 102 mounted on the hinge pin 78. Each blank moldsection 100 is connected through a link 104 (Figs. 21 and 22) to a rockarm 103, each link having a ball and socket connection at one end withsaid arm 103 and at the other end with an extension-105 on the mold arm101. These rock arms 103 (Figs. 2, 6 and 21) are fixed to a transverserock shaft 106 journalled in bearings 107 on the slide 67. One end ofthe rock shaft 106 extends beyond the rock arm 103 and carries a shortrock arm 108 mounting at its outer end a cam roll 109 running in thepath of an adjustable cam 110. This cam 110 is removably secured to asupporting block 111 slidably mounted for vertical adjustment, ashereinafter described, in a guideway 112 formed in the outer face of oneof the columns 61 of the mold supporting frame. The cam path is formedwith an offset 113 (Fig. 22) which, during downward movement of theblank mold unit causes rocking of the arms 108 and 103 and through thelinks 104 opens the blank mold.

In order to vary the elevation at which the blank mold opens and closesand thereby predetermine the extent of exposure of a blank to theatmosphere, this cam 110 is adjustable verticaly by means of anadjusting screw 114 (Figs. 9 and 10), the upper end of which is threadedthrough a bracket 115 on said cam while the lower end is journalled in abearing 116 and carries a bevel gear 11'? running in mesh with a drivingbevel gear 118 which is rotatable in either direction by a hand wheel119. The cam carries a pointer 120 movable over a graduated scale 121whereby the operator is guided in his adjustment of the cam so that itssetting may be accurate and properly related to the height of the neckmold 95 as indicated by the pointer 122 (Fig. 9) and a graduated scale123 which shows the height of a the blanks being formed. Thus, theblanks may be retained in the blank mold or exposed to the atmospherefor any desired portion of the period ,pipe 128 to the upper end of themotor 423.

of downward movement of the blank mold to the to change the elevation ofthe cam 110 determines the point at which the blank mold opens.

Associated with each mold unit, is a plunger and controlling mechanismtherefor, as shown in Figs. 1, 2 and 11 to 13, inclusive. 'I'he'arm '76which supports the hinge pin 78 is formed with a head 420 on its upperside having transversely aligned stub stafts 421 (Fig. 13) rotatablymounted therein and supporting'a forwardly extending arm 422 forvertical swinging movement about the common axis of said shafts. An airmotor 423 is carried at the outer end of the arm 422, a differentialpiston 124 therein being reciprocable vertica'ly to transmit acorresponding movement to a plunger rod 81 which is connected to thepiston and depends therefrom. Constant air pressure is applied to thelower side of the differential piston 124 through a supply pipe 125(Figs. 2 and 5) from the air pressure chamber 126 by way of a valvedport 127 in the wall of the motor cylinder to thereby normally hold theplunger rod 81 in its uppermost position. A pipe 160 continuouslyconveys air pressure to the chamber 126. At predetermined timeintervals, air pressure is supplied from the chamber 126 through a pipe128 and valved port 129 to the upper end of the motor cylinder to movethe piston 124 and plunger rod 81 downwardly (Fig. 11). Such movement ofthe plunger rod projects the plunger tip 130 into the neck mold cavityto form an initial blow opening in the blank as is customary.

The valve mechanism controlling the supply of air pressure to the motor423 is shown in Figs. 1 and 7 as comprising a pair of vertically spacedinterconnected valve disks 131 adapted to alternately open and closeports 132 and 133 in vertically spaced transverse wa ls of a valvehousing 134. The upper port 132 communicates directly with the airpressure supply chamber 126 while the lower port 133 communicatesthrough a series of openings 135 with the atmosphere. A coil spring 136normally yieldingly holds the upper valve disk 131 in a position toclose the upper port 132 so that except at predetermined intervals, airpressure is not transmitted through the A push rod 137 axially alignedwith the two valve disks, bears against the lower side of the lowervalve disk 13 1 and rests upon a lever 138 pivoted at one end to adependingflnger 139 on the valve housing. The other end of this levercarries a one of the cams 58 mounted on the upper side of theaforementioned cam table.57. It is underpass through the pipe 128 to theupper end of the cylinder of the air motor 423, thereby overcoming thepressure applied to the lower side of the piston 124 and causing theplunger tip to move downwardly as shown in Fig. 11. When the cam roll140passes beyond the cam 58,--the lever 138 moves downwardy lowering thevalve disk 131 and simultaneously closing the upper port 132. Thus, theair pressure above the piston 124 is exhausted through the pipe 128 andport 133 to the atmosphere, allowing said piston to again move upwardlyunder influence of the constant pressure applied through the pipe tothelower side of said piston.

A cap is slidably mounted on the' plunger rod 81 and normally rests uponthe outer shell or frame 79 of the gathering head, the lower portion ofsaid cap being spaced laterally from the plung er rod 81 and providing achamber 146 communicating directly with the chamber within the fa-'pered sleeve 80. A coil spring 147 encircling the upper portion of theplunger rod 81 normally yieldingly holds the cap 145 snugly seated uponthe frame 79 and in .spaced relation to the air motor .423. The upper.portiomof the cap 145.

is formed with a pair of opposed ports 148 (Figs. 5 and 12A). One ofthese ports communicates through a pipe line 150 (Figs. 2 and 5) withthe vacuum chamber 149, and the other with the, air pressure chamber 126through a pipe line 151, the latter provided with a valve 151' to assistin regulating flow of air pressure through the pipe.

The vacuum and air pressure pipes 150 and 151. respectively, eachcomprise a pair of sections interconnected by axial openings 152 in thestub shafts 421 (Fig. 13) The outer ends of the openings 152 areconnected to the outer sections of the vacuum and air pressure pipes 150and 151. These openings 152 communicate through radial ports 153 withannular channels or ways 154 which areat all times in register withports 155 to which the inner sections of the vacuum and air pressurepipes 150 and 151, respectively, are connected. The stub shafts 421 aresecured to the inner end of the arm 422 (Fig. 13) by set screws 156 orthe like elements and have their inner ends journalled in bearingsformed in the head 420. The inner sections of the air pressure andvacuum pipes each includes a pair of telescopic sections permittingvertical adjustment of the blank forming elements without interruptingcommunication between the vacuum and air pressure chambers and the neckmold.

The plunger rod 81 is formed with an axial passageway 157 opening at itslower end through a series of downwardly and outwardly inclined ports158. The lower end of the plunger rod is formed with downwardly taperedfaces 159 which seat upon the inner face of the sleeve 80 when theplunger tip 130 is projected into the neck mold 95.

The upper end portion of the axial passageway 157 communicates with aradial port 161 (Fig. 11) This port 161 is inregister with a port 148(Fig. 12A) at times, the latter leading to the vacuum pipe 151 wherebythe mold cavity may be vacuumized when the plunger tip 130 is projectedinto the neck mold as shown in Fig. 11. Spaced below the port 161 isanother radial port 162. Upon upward movement of the plunger to theposition shown in Fig. 12, this lower radial port 162 is brought intoregister with the port 148 leading to the air pressure pipe 151. Thus,the elements are alternately positioned to permit application of airpressure and vacuum to the mold cavities at proper intervals.

The vacuum control valve (Figs. 1 and 23) is arranged in the vacuum pipe171 leading into the vacuum chamber 149 by way of an opening in theinner wall of said chamber. The pipe 171 (Fig. 25) is threaded into anopening 173 in the upper end of an extension 172-on the top plate- 60,formed with an opening 173 adapted for register during the period ofapplication of vacuum with a longitudinal slot 174 formed in the innerwall of thewacuum chamber' l49. A cam controlled push rod 175 is mountedin suitable bear- 1,97e,sas

ings 176 at the upper end of said extension 172,

said rod having its inner end connected through a link 17': to a lever17:; can-led by the valve This push rod 175 carries a cam roll 179 whichrides over a cam 180 during the period of vacuum application. This cam180 (Figs. 23, 25 and 26) comprises two circumferentially adjustablesections 181 and 182 arranged upon the upper wall of the vacuumchamberand rotatable with the mold carriage. This adjustable section 182is movable over the other section 181 and is formed with a longitudinalvertical slot 183 through whichsecuring bolts 184 extend and bywhichthis section 182 may be locked at any desired point to thereby; controlthe length of the period of application of vacuum. The other section 181is adjustable. circumferentially 'to permit advance or retardation ofthe point at which vacuum is first applied. A coil.

spring 185 arranged between the inner bearing 176 and a collar 186 fixedto the push rod 175,

. serves to hold the vacuum valve 170 closed except when thecorresponding gathering head is in charging position. 7

After termination of the application of vacuum and the plunger isremoved from the neck mold, blowing air is applied through the airpressure .pipe' 151, such application being controlled by a valve 190(Fig. 2) which provides communication between the air pressure pipe 151and the air pressure chamber 126 through a port in the bottom wall ofsaid chamber. This valve 190 is periodically opened by a lever 191fulcrumed to a bracket 192, said lever can'ying a roller engaging thestem 193 of the valve and the other end carrying a cam roll 194 which isperiodically engaged by a patch on one of the cams 59 (Figs. 2 and 43).With such engagement between the cam roll 194 and one of the campatches, the valve 190 is opened to thereby permit flow of air pres:sure through the pipe 151 to the blowing head and neck mold to form theinitial blow opening in a blank. Frequently the blanks are of such sizethat the plunger alone forms a sufliciently large initial blow openingand the blowdown following removal of theplunger is unnecessary. Underthese conditions, one or more of the cam patches are removed so thatblowdown air pres-- openings 196 formed in an upward arcuate extension197 on the head 420 (Fig. 11), said plunger being carried by the arm422. Thus, it is seen that the air motor 423 and ,the other plungercontrol mechanism may-be held at any desired elevation while replacingor repairing parts there of.

' 'The cut-oil mechanism" which severs the charges from the supply bodyof glass and closes the blank molds, is mounted upon the outer end of aradial arm 200 supported on one ofthe mold frame columns 61. This armcarries at its outer end an air motor 201 (Figs. 2 and 27), the lowerend of the motor cylinder 360 (Fig. 9) being formed with a dependingtubular guide 202. A diiferential piston 203 is arranged in the motorcylinder and carries a relatively long piston rod in the form of ahollowshaft 204, extending downward through the guide 202. This shaft 204 "isformed with a longitudinal channel or way 205 in its-periphery intowhich a pin 206 projects to thereby prevent relative rotation betweensaid shaft 204 and guide 202. The cut-off knife 207 is fixed to thelower end of a rod 208 which extends upwardly through the tubular shaft204 and piston 203 and has its upper end threaded for engagement with ahand wheel 209, the latter being operable to vary the elevation of theknife 207. This hand wheel is formed with a radial peripheral rib 210 atits lower end which is taken .over by a suitable retaining flange 211secured to the head 212 of the air motor cylinder.

Interposed between the knife carrying rod 208 and the tubular shaft 204is a sleeve 213 having a flange 214 at its upper end bearing against thelower end of the hand wheel and holding said sleeve against longitudinalmovement. Relative rotation of the sleeve 213 and the knife carrying rod208 is prevented by a vertical slot and pin connection 215 which permitsvertical adjustment of the knife and rod relative to said sleeve. Anangular slot 216 (Fig. 27) formed in the sleeve 213, slidingly receivesa pin 217 extending radially inward from the tubular shaft 204. Withreciprocation of the piston 203, the tubular shaft 204 iscorrespondingly moved in the guide 202 so that an oscillatory movementis transmitted to the knife 207 through the sleeve 213 and rod 208.

Constant air pressure is applied to the lower side of the piston 203(Fig. 27) through the air pressure pipe 125 and a valved port 218adjacent the lower end of the air motor cylinder 360. This pipe 125, aspreviously stated, communicates directly with the air pressure chamber126 (Fig. 2) to which air pressure is continuously supplied through apipe- 160. A pipe 219 (Fig. 5) periodically supplies air pressure fromthe chamber 126 to the upper end of the air motor cylinder 201 by way ofa valved'port 220 (Fig. 27) adjacent the upper end of said cylinder. Avalve (not shown), similar to that shown in Fig. '7, and operableperiodically by a cam 221 spaced outwardly from the cams 58 on the table57 (Fig. 1) regulates application of air pressure to actuate the cut-offmechanism.

The finish mold (Figs. 1 to 4, inclusive) of each mold unit includes a.hollow frame 230 formed with a pair of arms 231 (Fig. 3) which arejournalled on stub shafts 232 mounted in bearings 233 formed in the moldframe columns 61. Each stub shaft 232 is hollow throughout a majorportion of its length and opens into the chambers formed in the arms 231of the finishing mold frame. Each stub shaft and the correspondingbearing 233 have aligned radial ports 64 by which communication isestablished between the hollow arms 231 and the air pressure chamber 53(Figs. 2 and 3). A cap plate 234 is affixed to the outer end of the stubshaft 232 and is bolted or otherwise secured to the column 61. Thus,provision is made for the application of cooling air through thefinishing mold arms 237 on the main frame to the finishing mold sectionsin a manner well known in the art and therefore not detailed in thepresent application. The finishing mold sections 235 are mounted on acommon vertical hinge pin 236 (Fig. 2) and are connected by links 249 tohollow arms 237 which extend rearwardly and communicate with the airchambers in the arms 231 of the finishing mold frame. These mold sectionsupporting arms 237 are connected through a link mechanism 243 to aslide 238 movable radially of the mold carriage in guideways 239 by thecam 55 on the stationary central pillar, said cam periodically movingthe slide 238 radially outward through the medium of a cam roll 241(Fig. 2) and thereby alternately opening and closing the molds. l

Each of the supporting arms 231 of the finishing mold frame is formedwith a gear segment 242 at its inner end running in mesh with one of therack bars '74 which is slidable vertically in a suitable guide 361,which guide extends downwardly to the lower side of the correspondingair pressure chamber 53. Thus, vertical swinging movement of thefinishing mold frame transmits through the gear segment and rackbar,vertical movement tothe blank mold unit so that the'neck and finishingmolds may be alternately brought together and moved apart at properintervals.

The finishing mold unit carries a roll 244 in suitable bearings 245 onits lower side, said roll running on a serpentine track 246 suitablysupported on the circular stationary base 51. For reasons hereinafterapparent, there is provided a yielding adjustable connection between theroll 244 and the finishing mold frame 230. This connection comprises a'pair of telescopic sections 247 (Fig. 1) having pin and slot connectionto each other and normally held 'at their outermost limits by a spring248. This unit, including the roll 244 may, be adjusted verticallyrelative to the finishing mold frame 230 by any preferred means (notshown). One mechanism for effect ing adjustment between this unit andthe finishing mold frame is disclosed in Patent No. 1,185,- 687, grantedJune 6, 1916, to R. LaFrance; to which patent-reference may be had fordetails. Each finishing mold unit is provided with removablecounterweights 362 which assist in lowering the mold at regularintervals. I

The track 246 (Fig. 40) which alternately raises and lowers thefinishing mold unit, is of such shape that when the .roll 244 reachesthe area 250 thereof, the finishing mold swings downwardly andtherebylifts the gathering mold to a plane above the gathering area 251of the supply body of glass in the trough 252. Movement of this roll 244up the short incline 253, lifts the finishing mold and through the rackand gear mechanism lowers the blank mold a corresponding degree, causingthe latter to dip into the glass. This dip or gathering position ismaintained for a period of time determined by the length of the raisedportion 254 of the track. This particular portion 254 is formed with alongitudinally adjustable section 255 having slidable connection to theadjacent ends of the track 246. One end portion of the track and theadjustable section are formed with bearing blocks 256 (Figs. 16, 17 and18) mounting an adjusting screw 257 having aknurled finger piece 258 bywhich the screw is rotated to shift the adjustable section 255 tothereby lengthen or shorten the raised portion 254 of the track 246, andthereby control the length of the gathering operation. This adjustablesection 255 is inclined at 255 so that it causes lowering of thefinishing mold after a charge has been gathered, and consequently liftsthe blank mold out of the glass. At a predetermined station 259 beyondthe gathering trough 252, the finishing mold is lifted to its uppermostlimit into engagement with the neckmold of the corresponding unit. Atthis station 259, the article formed in the molds during. the cycle justcompleted is transferred from the finish mold, 145

mold is held in engagement with the neck mold 50 95 by a lock devicewhich cooperates with the rack bars 74 (Fig. 2) as will be pointed out.

This locking device (Figs. 44 and 45) comprises a pair of arms 261interconnected by a hinge pin 262 depending from the air pressurechamber, said arms having fingers 263 connected by links 264 to a pushrod 265 carrying at its inner end a cam roll 266 adapted for alternateperiodic engagement with. circumferentially,

spaced cam sections 240 and 240 (Figs. 1, 2, 44 and 45). Each arm 262 isformed with a fume.- tion 267. which straddles the lower end of one ofthe rack bars 74, said rackbars having their lower ends 268 formed toreceive said furcations. The natural tendency of the rack bars 74 tomove upwardly under influence .of the weight of the finish mold frame230, frictionally holds the locking device in engagement with the rackbars and obviates the necessity for providing along continuous cam asa-positive means for holding the locking devices in operative position.when the finish mold reaches the ware ejecting station,

- the cam roll 2 66 (Fig. 44) strikes the stationary cam'240 and causesswinging of the arms 261 into locking engagement with the lower ends ofthe rack bars 74 so that the finish mold and neck mold are interlocked.During movement of the finish mold between the two cam sections 240 and240 (Fig. 40), the cam roll carried by the finish mold is spacedslightly above the serpentine 'track so that connection between thefinish and neck molds is solely dependent upon the locking device, thedepressed portion of the track merely being provided as a precautionarymeasure. Upon engagement of the cam roll 266 with the cam 240'-,-thearms 261 are moved away from the rack bars 74 so that the finish moldmay be lowered away from the neck mold and thereby permit closing of.the blank mold into engagement with the neck mold preparatory togathering another charge of glass.

In the production of glassware on a machine of the above character, themold carriage is continuously rotated to thereby bring the mold units insuccession to a position in proximity to the trough 252 containing thesupply body 251 of molten glass. As a mold unit approaches the gatheringstation, the finishing mold is first lowered by the dip 250 in .theserpentine track 246 (Fig. 40) to thereby elevate the blank mold 100 toa plane in which it may pass over the rim of the trough. The finishingmold is'then raised slightly by the high portion 254 of the serpentinetrack 246 to thereby transmit through the racks 74 and gear segments242, a movement causing the blank mold to dip into the supply body ofglass. Just prior to charge gathering contact between the blank mold 100and the molten glass in the trough, the rock arms 103 (Fig. 22) aremoved forwardly to close the blank mold; the

plunger 130 a projected into the neck mold; by

downward movement of the piston 124 of the air motor 423; and the neckmold 95 is closed by radial outward movement of the cam plate 75 (Figs.1 and 19). The plunger 130 is lowered by application of air pressure tothe upper side of the piston 124, this airpressure being supplied fromthe chamber 126 by way of a valve such as shown in Fig. 7. fiis fgalveremains open during and for a short period following the gathering of acharge of glass. While .the elements are relatively positioned as aboveoutlined, the vacuum control valve 170 (Figs. 1 and 23) is opened by thecam 180 to thereby permit application of vacuum to the blank mold in anobvious manner.

4 Upon completion of the charge gathering operation, the finishing 'moldis lowered due to the presence of the downward inclination of theadjustable track section 255 (Fig. 40) so that the blank mold is liftedabove the surface of the 8 supply body of molten glass, such lifting ofthe mold being combined with lateral movement thereof away from thegathering point. The cutoil. knife 207 (Figs. 5 and 27) which isnormally positioned at one side of the 'blank mold is swung 85 inwardlyto cut the string of glass from the bottom of the charge in the blankmold and to close the bottom of the blank mold cavity. This movement ofthe cut-off knife 207 is obtained by application of air pressure abovethe piston 203 (Fig. 96 27) which causes rotary movement of the knife207 as previously described. The vacuum may. be shut off at this pointdue to the cam 180 passii'.{beyond the valve 170. After the completionof the cut-oil operation and shut off of vacuum, at v pipes 151 anddownwardly through the axial passageway 157 in the plunger rod 81 (Fig.11). At

the end of the cam 59, the air pressure is cut off by closing of thevalve 190, and the cut-off knife 207 is swung laterally away from theblank mold. Just preceding this lateral movement of the knife. the blankmold is raised slightly away from the knife due to slight lowering ofthe finish mold which is caused by a drop 300 in the serpentine track246 (Fig. 40)

Immediately following the removal of the cutoff knife-207, the finishmold, under influence of the serpentine track 246, begins to moveupwardly toward the blank mold. The blank mold, as is understood fromthe foregoing description, also moves downwardly at a speedcorrespondingto that of the upward movement of the finishing mold due to the rack andgear'segment between the blank and finish mold units. At a predeterminedelevation, the rock arm 108 (Fig. 22) moves into the offset 113 in thepath of the cam 110 so that the depending rock arms 103 are movedradially inward causing opening of the blank mold 100 and suspension ofa bare formed parison from the neck mold 95. Continued relative movementof the blank and finish mold units toward each other, brings the finishmold sections 235 to a position at which they are moved inwardly towardeach other to enclose the bare suspended parison. This closing movementof the finish mold is effected by the stationary cam 55 (Fig. 2) whichcontrols movement of. the slide. 238, the latter being connected to themold arms 237 by link mechanism 243 well known in the art.

Upon complete closing of the finishing mold about the parison, thelocking device shownin 14o Figs. 44 and 45 and including the furcatqiarms The finished articles are automatically removed from the finishingmolds and deposited upon a suitable conveyor or ware handling device ata predetermined station by a take-out mechanism such as that shown inFigs. 31 to 39, inclusive. The take-out mechanisms are individual to themolds units and, as will be apparent, are adjustable as required by thetype and size of ware being produced on the corresponding mold unit.Each take-out mechanism comprises a relatively long bearing sleeve 301mounted on the outer end of a supporting arm 302 (Figs. 1 and 2), thelatter being bolted or otherwise rigidly secured to the finishing moldframe 230. This bearing sleeve 301 is formed with an angular slot 303(Fig. 39), there being provided a short straight portion 304 at theupper end of said slot for a purpose hereinafter apparent. A guide 305extends upwardly from and axially of the bearing sleeve 301 (Fig. 36),said guide being removably secured to the bearing 301. This guide 305 isformed with a transverse slot 306 adjacent its upper end for a purposehereinafter pointed out. A shaft 307 extends through the bearing sleeve301 and at the upper end of said sleeve is reduced in diameter, formingan annular shoulder 308 which abuts the lower end of the guide 305. Thereduced end 309 of the shaft is extended through said guide and has itsupper end screw threaded for threaded engagement with collars 310 whichsupport an arm 311 carrying the ware gripping jaws 312. The lowersection of the shaft 307 within the bearing sleeve 301 removably carriesa roll 313 which extends radially therefrom and moves in the angularslot 303. The lower end of the shaft 307 is secured to a bottom plate"314 formed with a depending finger 315 carrying a stub shaft 316 onwhich the cam roll 317 is mounted. This cam roll 317 is adapted forperiodic engagement with a cam 318 (Fig. 41) which causes downwardmovement and consequent partial rotation of the shaft 307 atpredetermined intervals. The shaft 307 is yieldingly normally held inits uppermost position by means of a coil expansion spring 319whichencircles the reduced end 309 of the shaft 307 between the guide 305 andan adjustable collar 320. The ware gripping jaws 312 are journalled onstub shafts 321 carried on the outer ends of angular arms 322 (Fig. 32),the latter being mounted on a vertical hinge pin 323. Each jaw 312includes an upstanding flange 324 formed with an arcuate channel 325 inits upper edge to receive a pin 326 extending inwardly from a bearingplate 327 on the corresponding supporting arm 322. Thus, relativeswinging movement between the jaws 312 and their supporting arms 322 islimited.

The main supporting arm 311. according to the present embodiment of theinvention, is substantially L-shaped, as shown in Fig. 32. The laterallydirected outer portion 328 is formed with longitudinal guides 329 for aslide 330 whose outer end is connected by links 331 to the arms 322which carry the jaws 312. The inner end of the slide 330 is connectedthrough an adjustable connector 332 to the outer end of the rock arm333, pinned or otherwise rigidly secured to a supporting rod 334 whichextends downwardly through a bearing 335 formed in the take-out arm 311,the lower end of said rod 334 being extended through a guide sleeve 336.A coil spring 337 above the rock arm 333 has its outer end connected toa pin 338 rising from the outer end of said rock arm, while its innerend is suitably connected to a pin 339 on one of the collars 310 whichmount the take-out arm 311 on the shaft 307. The function of this spring337 will be apparent hereinafter. The guide sleeve 336 (Fig. 36) whichreceives the lower end of the rod 334 is splined to the latter and inturn is journalled in a short vertical bearing 340 supported on an arm341 which extends radially from a collar 342 mounted on the reduced end309 of the shaft 307 in the transverse recess 306 in the guide 305. Thiscollar 342 carries a pin 343 which projects into a longitudinal way 344whereby the shaft 307 is permitted to move vertically relative to thecollar 342 and to rotate therewith as a unit. A collar 345 rests uponthe bearing 340 (Fig. 36) and encircles the upper portion of the guidesleeve 336 to which it is rigidly secured by a pin 346 or the like. Avertical pin 348 is carried by the upper portion349 of the guide 305 andextends through an arcuate slot 350 in an adjustable plate 351 whichcarries anotherpin 352 at a point spaced circumferentially from the pin348. This plate 351 is formed with a slot 353 at a point spaced from thefirst pin 348, said slot receiving a set screw 354 which permitsrotation of the plate 351 and consequent placing of the two pinsrelative to each other as required by operating conditions. A radialfinger 347 on the collar 345 is at all times disposed between the twopins 348 and 352.

In operating this take-out mechanism, the adjusting collar 355 is set toproperly elevate the take-out arm 311 and jaws thereon in accordance'with the height of the articles to be removed from shaft 307 of thetake-out device is pulled downthe latter is gradually lowered so that atthe extreme inner end of its swinging movement, the jaws 312 arepositioned at opposite sides of the neck of the article in the finishingmold. At the moment this position of the jaws is assumed, the radialfinger 347 (Fig. 38) strikes the .pin 352, causing the rock arm 333(Fig. 32) to swing to the left and thereby close the jaws 312 as shownin Fig. 32. At this period, the finishing mold opens and simultaneouslytherewith the shaft 307 moves upward under influence of the coilexpansion spring 319. This upward movement is again combined with arotary movement on the part of the shaft 307, causing the take-out arm311 to swing upwardly and laterally away from the finish mold,positioning the removed article directly over 'a conveyor 0 other warehandling device 260. At this point, the finger 347 (Fig. 37) strikes thepin 348 which causes the rock arm 333 to swing to the right and therebyopen the jaws 312 and deposit the article upon said conveyor.

The coil spring 337 (Figs. 31 and 32) assists in swinging the arm 333 toits outermost positions to thereby positively actuate the ware grippingjaws 312. It is seen that when the arm has been rocked beyond a centerline running through the axes of the pin 339 and rod 334, the spring 337will quickly snap thearm to one of its outermost positions and therebyopen or close the jaws 312.

By adjusting the length of the connector 332 (Fig. 32), the extent towhich the jaws 312 close may be varied as required by the diameter ofthe,
